PRINTERS COLUMN-RULE.

Specification of Letters Patent.

Patented Jan. 5, 19115.

Application led April 1, 1914. Serial No. 828,893.

To all whom it may concern Be it known that we, WILLIAM LoviiLAND andHARRY ELLwooD SLoAN, citizens of the United States, residing atPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have jointly invented a cern tain new and useful Improved PrintersColumaRule, of which the following is a specification.

This invention relates to rules such as are used by printers in makingup in a chase, columns of type or other matter. Such rules, as atpresent manufactured, are of one-piece construction provided with ashort, thick Vshaped impression face and are generally unsatisfactoryfor the following reasons: Because of the great pressure exerted upon.the contents of a chase when an impression is being made upon a mat ormatrix, either of the wet or dry variety, hardened steel rules are morelasting, but become corroded in use, due to moisture to which they aresubjected. If non-corrosive rules, as for instance of brass, are used,the metal being relatively soft, the impression face of the rule isuseless once the impression edge becomes worn. Possibly a greaterobjection resides in the fact that the faces of rules as at presentmanufactured, when used for impressions upon mats or matrices, either ofthe wet or dry variety, frequently fracture or otherwise mutilate orsever the fibrous material of the mats or matrices thus necessitatingthe making of a new mat for casting purposes. Further it frequentlyhappens that when impressions are being made, the body portion of therule is embedded in a mat, thereby ruining said mat.

The principal objects of the present invention are to overcome the abovedescribed disadvantageous features and provide, first, a printers columnrule, which is practically eiiicient for the purposes intended and whichembraces features, whereby hardened steel impression members may beinterchangeably fitted to non-corrosive rule bodies. Second, to providea printers column rule, the impression face of which is so designed thatdesired impressions may be vmade upon mats without fracturing thefibrous construction thereof. Third, to provide such a rule soconstructed that the rule-body acts as a stop to prevent saine beingembedded in a mat.

l/Vith these and other objects in view, the invention consists of theimprovements hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will bemore fully understood from the following description taken in connectionwith the accompanying drawings forming part hereof and in which:

Figure 1, is a view in side elevation of arule eXact size) embodying theinvention. Fig. 2, is an end view thereof. Fig. 3, 1s a fragmentaryview, partly in elevation and partly in section, drawn to an enlargedscale, of one end of the rule. Fig. a, is a view in cross-section, drawnto a much exaggerated scale and illustrating the parts in position forbeing assembled, and Fig. 5, is a similar view of the parts assembled.

Referring now to the drawings in detail 10, designates the rule-bodywhich in practice is usually brass, due in part to its noncorrosivecharacter and also for the reason that it may be easily worked toprovide for the reception and holding in place of detachable impressionfaces to be presently described. One longitudinal edge of the body 10,is milled out throughout its length to provide a groovell, to which isfitted a continuous, very thin, hardened steel impression member 12.This member being very thin, the cross-section therof is very narrow andthroughout the length of the member 12, and upon both sides thereof,from its impression edge to about midway its height, said member isslightly tapered as at 13, to further reduce its cross-section andprovide the desired impression face. As clearly shown in assembling therule, the tapered part of the member 12, extends slightly within thegroove 11, of the body 10, so that this part of the member 12, is notclosely hugged by the groove walls. To relatively interlock the partstogether, the rule-body upon both sides thereof and throughout itslength is slightly depressed, as at 14, by suitable means, so that thegroove walls are caused to closely hug that tapered part of the member12, contained therein, see Fig. 5. One end of the body l0, may benotched as at 16, immediately below and communicating with the groove1l, so that a suitable implement may be inserted to pry loose a wornmember 12, so

that a new one `be fitted to placelwAs before stated, brassbeingrelatively soft, new members' l2, may be readily forced within thegroove 11. very narrow, tapered cross-section of the member l2, the matsused to receive the desired impressions, readily accept such a memberwithout having the fibrous mat texture fractured or otherwise mutilatedas frequently occursby the use of the relativelybroad faced rulesnow' ingeneral use. In' this connection, itis to'be further noted, that thedat' top of the rulebody, at the parts designated 15, forms shoulderswhich serve vto'act asstops to prevent the body cutting into'amat.' Bybeing able to repla'cewworn' impression members with new ones,"the bodyportion `rof the rule may be used indefinitely, and since new impressionmembers'rnay 'be' readily fitted to place at little Tcost,` a'gr'eatsaving and'betterwork iii'printin'gis possible'by lthe above columnrule.

lllhat we claim is J1; Aprintersjkcolumn rule embracing a body portionfhaving a squared top edge, whichf'top edge is longitudinallyf'groovedthroughout the `'entire'length of said body portioiifand a thingradually tapered impression strip removably fitted to saidgrooveftheworlr'end of said strip being projected 'x an appreciabledistance beyond the squared top `edge of the rule, whereby atp'thejuncture point of said squared edge and impression l strip shouldersforming stopsare provided. u

ZIA printers .column rule embracing a bodyI of. relatively soft metalsaid bodyhaving ajs'quared top edge, which top edge 'is longitudinallygrooved throughout the eiitire length of.` said body portion, and a thinimpression strip of relatively hard metal removably ftted to said groovethe work end of said strip being projected an appreciable distancebeyond the squared top edge of thei'l rule, whereby at the juncturepoint offsaidwsquared edge and impression' strip shoulderspforniingstops are provided.v

Ai printers column' rule embracing a bedr` perdn having e .Square ter,edge, which top ,edge is 'longitudinally grooved throughoutthe entireylength of said body portion', and a thin'mgradually tapered impressionstrip Aremovably fittedI to said groove 1the 4vvorlfrend of said stripbeing P're'iee. edf'eln" eprleeeble' deenee beyond the "squared topedgepof the rule at least a p'eittiee'efjthe tapered, reife' ef SeidStrip beili'gcoiitained 'within said groove.

By reason of the" LMA printers column rule embracing a body portion ofrelatively soft metal the squared top edgeof which is longitudinallygrooved to removably receive a thin slightly tapered impression strip ofrelatively hard metal the work end of which is projected an appreciabledistance beyond the squared top edge of the rule at least a portion ofthe tapered part of said strip being contained within said groove.

5. A printers columny rule embracing a bodyupo'rtion having squaredbottoin and top edges the upper squared edge being longitudinallygrooved "and a narrow slightly tapered impression strip removably littedto said groove a portion of its tapered part being` contained withinsaid groove andy a portion thereofbeing projected above said squared topedge.

6.'.A pri'nters column rule embracing a rectangular body portion havingsquared bottom and top edges the top .edgebeing longitudinally grooved,to Iremovably receive a slightly tapered, impression strip of'aVcross-section smaller than the body cross-section, of which a portionof said tapered strip is contained within said groove and of which aportion thereof projects beyondthe squared top edge of the body, wherebyat the juncture pointI of said square edge and impression strip,shoulders or stops are`provi'ded. j I,

A printers column rule embracing a body portion having squared bottomand top edges the upper squared edge being longitudinally groovedthroughout its entire lengthy and a thin slightly tapered impressionstrip removably and snugly fitting said groove with at least a portionofI said tapered part contained within the groove and the remainingtapered part projected above the' upper squared edge the side walls ofthe body being longitudinally compressed adj acentl the body top torelatively interlockthe impression strip with respect to the body.

8."A printers column rule embracing a body portion having a squaredlongitudinally grooved top edge at least one'end of saidv body portionbeing notched immediately'bel'o'w and in communication with said grooveand a thin impression strip removably iitted to said groove.

Intestimony whereof, we have hereunto signed our names.
